A gate may make use of one or more logs. Each log is lowered horizontally into a space or bay between two grooved piers referred to as a stoplog check. [3] In larger gate structures, there will be multiple bays in which stoplogs can be placed to better control the discharge through the structure.
Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams , to adjust flow rates in sluices and canals , or they may be designed to stop water flow entirely as part of a levee or storm surge system.
A notch weir is any weir where the physical barrier is significantly higher than the water level except for a specific notch (often V-shaped) cut into the panel. At times of normal flow all the water must pass through the notch, simplifying flow volume calculations, and at times of flood the water level can rise and submerge the weir without ...
The volume and speed of water down the river is managed by adjusting the gates at each weir. Occasionally this can result in a fast stream rendering navigation more hazardous. These conditions are indicated by yellow or red warning boards on the lock gates and the status of all locks is published by the Agency. [4]
The wire is aligned under tension between heavy, braced, fence posts (strainer posts) and then held at the correct height by being attached to wooden or steel fence posts, and/or with battens in between. The gaps between posts vary depending on type and terrain.
In hydraulic engineering, a nappe is a sheet or curtain of water that flows over a weir or dam. The upper and lower water surface have well-defined characteristics that are created by the crest of a dam or weir. [1] Both structures have different features that characterize how a nappe might flow through or over impervious concrete structures. [2]
